Patrick Murphy, the likely Democratic nominee in Florida's 18th district, raised an impressive $508,000 in the second quarter of 2012 in his bid to unseat outspoken GOP Rep. Allen West. Murphy's campaign will announce the numbers later today.

The businessman, a former Republican, ended June with just less than $1.3 million in cash on hand. He ended March with just more than $1 million in the bank.

West ended March with more than $3.3 million in cash on hand. He does not appear to have released his second quarter numbers yet. Filings are due to the Federal Election Commission on Sunday.
